Completely unrelated story...skip if you like.

About ten years ago we put a hardwood floor in Wayne and Connie's house. Wayne and I are tearing out the old floor and after pulling out a crowbar that we'd just driven in, a loud hissing came from the basement. Wayne and I looked at each other and immediately we both yelled "GAS" at the top of our lungs and yelled for Connie and the kids to get out of the house. We arrive in the front yard and Connie looks at us and says, "What is the gas from? I thought the furnace was electric."

She was of course right....It's an all-electric home......The hiss was a freon line we'd punctured.
